But the technology landscape […] In NAC, protocols and policies are used to define and implement rules that determine which devices and users can access the network, based on the rules. This practice is not recommended because the broadcast domain of the management IP address and the traffic IP address is resided within the same Local Area Network (LANs). Organisations discovered a binary system that worked well by either allowing or denying devices access to the network. You could choose to stop all traffic in one part from reaching another, or you can limit the flow by traffic type, source, destination, and many other options. When you create multiple segments behind Cisco firewalls, a best practice is to explicitly deny traffic from lower-trusted segments to higher . with today's network threats. The 5-4-3 rule is used in 10Base2 and 10Base5 Ethernet architectures. The ACS server, Policy Server, and OfficeScan server must be on the same network segment to ensure effective communication.
